使用at89s52单片机，采用GPIO管脚模拟i2c总线读写AT24c01eeprom.少经改变就可以用于读写AT24Cxx系列的EEPROM。已经用于工程实践，读写AT24C01有效可靠。用于存储一些配置信息，128字节的at24c01是一个很好的选择。模块化的程序，也很容易移植，里面有丰富的注释-Use AT89S52 microcontroller, GPIO pin used to read and write analog i2c bus AT24c01eeprom. Less by the change can be used to read and write AT24Cxx series EEPROM. Has been used for engineering practice, effective and reliable read and write AT24C01. Used to store some configuration information, 128 bytes of at24c01 is a good choice. Modular process, is also very easy to transplant, which is rich in Notes
